Shark Fiord is a deep, glacially-carved saltwater fjord on southern Baffin Island, Nunavut, functioning as a significant northern arm of Cumberland Sound. The fjord's southeastern shore is fairly low, with elevations around 400 feet (122 meters), while its northwestern side and the shores of the islands within it are higher and more rugged. This geography creates a dramatic, exposed environment with substantial fetch for wind to build waves. The water is deep and cold year-round, characteristic of high-Arctic coastal waters. As a remote Arctic location, there are no facilities, amenities, or established access points like launches or take-outs; reaching the water requires significant expedition planning and likely the use of a support vessel. The area is noted for its Quaternary vertebrate fossils, indicating a landscape rich in paleontological significance. For paddlers, this is an extreme and committing expedition destination suitable only for highly experienced, self-sufficient teams prepared for Arctic conditions, including cold water, strong winds, and the complete absence of services or immediate rescue options. The environment itself presents the primary hazard.
